Temporary Waste Retention System

The Temporary Waste Effluent Retention System allows for temporary full retention of liquids, up to 3 days, entering a sump to be discharged overboard when the vessel has left a "No Discharge Zone." The system can be installed on vessels equipped with a Microphor MSD and Sump as well as other waste handling systems that utilize a sump to discharge liquid effluent. This system is designed for 120 volt AC voltage only.
